Find the measure of the missing angle 17
Answer:
<A =73
Step-by-step explanation:
The sum of the angles of a triangle are 180
<C is 90
<B is 17
We need to find <A
<A + < B + <C = 180
<A + 17+90 = 180
<A + 107 =180
<A = 180-107
<A =73

In a quadrilateral OABC, D is the midpoint of BC and E is the point on AD such that AE : ED=2: 1. Given that OA = a, OB = b and OC = c, express OD and OE in terms of a, b and c.
Answer:
Step-by-step explanation:
CB=OB-OC;
CD=CB/2=(OB-OC)/2=(b-c)/2;
OD=OC+CD=c+(b-c)/2=c/2+b/2;
AD=OD-OA=c/2+b/2-a;
AE=2/3*AD=2/3*(c/2+b/2-a)=c/3+b/3-2*a/3;
OE=OA+AE=a+c/3+b/3-2*a/3=a/3+b/3+c/3;
-------------------------------------------------------------------------------------------------
OD=c/2+b/2;
OE=a/3+b/3+c/3;
The value of OE = (a+ b+ c)/3 and OD = (b + c)/2.
In quadrilateral OABC, we are given that D is the midpoint of BC,
and E is a point on AD such that AE : ED = 2 : 1.
Also, OA = a, OB = b and OC = c
Now, By the Midpoint Theorem, we also have
OD = (1/2)OB + (1/2)OC.
OD = (1/2)(OB + OC)
OD = (1/2)(b + c)
OD = (b + c)/2.
and, CD= (OB- OC)/2 = (b-c)/2
Now, AD=OD-OA= (c+b)/2 - a
and, AE=2/3 x AD
= 2/3 x (c+ b)/2 - a
= (c + b - 2a)/3
Then, OE = OA + AE
= a + (c + b - 2a)/3
= (a+ b+ c)/3

what’s the answer to this question ?
Answer:
C
Step-by-step explanation:
Line pases through (6, 0) and (0, -6)
Slope = (0 - (-6))/(6 - 0) = 6/6 = 1
so y = 1*(x - 6) = x - 6
or x - y = 6
or 4x - 4y = 24
That is C

Consider the line x-7y=1
What is the slope of a line perpendicular to this line?
What is the slope of a line parallel to this line?
Answer:
Perpendicular slope: -7x
Parallel slope: 1/7x
Step-by-step explanation:
Rewrite this into slope-intercept form. So y=1/7x -1/7
Slope of a perpendicular line is the reciprocal of the original slope. So perpendicular line would be y=(-7)x-1/7. Slope in the perpendicular is -7. A parallel line will have the same slope,so basically y=1/7x-1 .
It doesn't matter what the y-int would be since a perpendicular/parallel slope only depends on the slope itself.
Answer:
[tex]\displaystyle \parallel\:\frac{1}{7} \\ \perp\:-7[/tex]
Step-by-step explanation:
[tex]\displaystyle x - 7y = 1 \hookrightarrow \frac{-7y}{-7} = \frac{-x + 1}{-7} \\ \\ \boxed{y = \frac{1}{7}x - \frac{1}{7}}[/tex]

Answer:
x = 9
Step-by-step explanation:
To Find the value of x and all angles :
We know that,
Sum of all angles of a triangle = 180°.⠀
Therefore,
[tex]{ \longrightarrow \sf \qquad \angle1 + \angle2 + \angle3= 180 {}^{ \circ} }[/tex]
[tex]{ \longrightarrow \sf \qquad (13x + 2) {}^{ \circ} + (5x - 7){}^{ \circ}+ (3x - 4) {}^{ \circ} = 180 {}^{ \circ} }[/tex]
⠀
Adding like terms we get :
[tex]{ \longrightarrow \sf \qquad (13x +5x + 3x) + { \bigg[2 + ( - 7) + ( - 4) \bigg]}^{ \circ}= 180 {}^{ \circ} }[/tex]
[tex]{ \longrightarrow \sf \qquad 21x+ ( - 9) {}^{ \circ}= 180 {}^{ \circ} }[/tex]
[tex]{ \longrightarrow \sf \qquad 21x = 180 {}^{ \circ} } \sf+ \: 9 {}^{ \circ}[/tex]
[tex]{ \longrightarrow \sf \qquad 21x = 189 {}^{ \circ}}[/tex]
[tex]{ \longrightarrow \sf \qquad x = \dfrac{189 {}^{ \circ}}{21} }[/tex]
[tex]{ \longrightarrow { \pmb{\bf \qquad x = 9 {}^{ \circ}}}}[/tex]
⠀
Therefore,
[tex] \longrightarrow \: \sf \qquad \angle1 = (13x + 2) {}^{ \circ}[/tex]
[tex]\longrightarrow \: \sf \qquad \angle1 = (13.9 + 2) {}^{ \circ}[/tex]
[tex]\longrightarrow \: \sf \qquad \angle1 = (117 + 2) {}^{ \circ}[/tex]
[tex]\longrightarrow \: \bf \qquad \angle1 = 119 {}^{ \circ}[/tex]

[tex]\longrightarrow \: \bf \qquad \angle2 = 38 {}^{ \circ}[/tex]
⠀
[tex]\longrightarrow \: \sf \qquad \angle3 = (3x - 4) {}^{ \circ}[/tex]
[tex]\longrightarrow \: \sf \qquad \angle3 = (3.9 - 4) {}^{ \circ}[/tex]

A line passes through the point (−4,5) and has a slope of −6.
Write an equation in slope-intercept form for this line.
Answer:
y = -6x - 19
Step-by-step explanation:
We can use y = m x + c to find the equation of the line.
Here,
m ⇒ slope
c ⇒ y - intercept
They have already given the slope of the line.
m = -6
And now we have to find the y - intercept using the given coordinates.
( -4 , 5 ) ⇒ ( x , y )
Let us find now.
y = m x + c
5 = -6 × -4 + c
5 = 24 + c
5 - 24 = c
-19 = c
Now let us write the equation of the line.
y = m x + c
y = -6x - 19
here a subtraction problem that has been solved incorrectly 21-9=11 choose the addition sentence that check this subtraction problem here the choices are 21+9=30 11+9=20 11+21=32 which one is correct
Answer:
Answer:
11+ 9 = 20
Step-by-step explanation:
=> 21-9=11
21 - 9 equals to 11 is actually a wrong answer
So in order to find the subtraction problem that will help us truly know whether the equation is wrong
=> 11+ 9 = 20

Each equation below is followed by several stories.
Select all of the stories that can be represented by the equation.
If none of the stories can be represented, select "None of the above".
(a)x+11=44
Typically, there are keywords in the story that tell us what operations we need to use.
For instance, in terms of age:
"Younger" or "older" connotes to subtraction from the age of the older person. It can also connote to the addition to the age of the younger person."Years ago" typically connotes to the subtraction of x years from the person's current age."More years" typically connotes to the addition of x years to the person's current age.Solving the QuestionLet's take a look at our first option.
Yousif is x years old. Rana is 44 years older than Yousif. Rana is 11 years old.Firstly, this option doesn't even make sense. How can Rana be 11 years old but also 44 years older than Yousif?
Let's look at our second option.
Rana is x years old. in 11 more years, she will be 44 years old.Immediately, we see "11 more years". This means that we will be adding 11 to Rana's current age, which is x:
[tex]x+11[/tex]
This expression above is equal to 44, since the question tells us that Rana will be 44 years old in 11 years:
[tex]x+11=44[/tex]
This is our final expression. It is the same as the given expression in the question.
AnswerRana is x years old. in 11 more years, she will be 44 years old.
